The laminated die r 5 male die may consist of a single strip. The thus formed may be used separately; but it female die, which is grooved, is a laminated is preferably connected to asolid inner form structure composed of a series of fiat strips 5 by pins or rivets 9, as shown in Fig. V, and secured together.

The male member of the apparatus a recess or groove is formed in one or both comprises an inner form 10 and a band 11, 7o faces of the die. which conforms thereto and projects below,

The mode of operation is illustrated in Figs. V and Vl. A suitably-shaped piece 16, of leather or other fabric, which is to form the insole is placed between the upper and lower members, as illustrated in Fig. V, and the members are then pressed together, the flange 12 creasing the fabric and forcing it into the groove S, as illustrated in Fig. VI.

2. In an apparatus for forming insoles, a female die consisting of inner and outer strips of suitable width, and intermediate strips of less width, all suitably connected together, substantially as described.

3. ln an apparatus for forming insoles, a female die consisting of suitably-shaped inner and outer strips of suitable Width, and intermediate strips of less width, the intermediate strips being arranged symmetrically with respect to the other strips, whereby grooves are formed be'tween the inner and out-er strips, all of said strips being suitably secured together, substantially as set forth.

i. In an apparatus for forming insoles, a female member comprising an inner form, a laminated die, having suitable grooves, se! cured to said form, and a block surrounding said die, substantially as set forth.
